The engineering of the spin state and axial coordination of the metal center of single‐atom catalyst (SAC) represents an effective strategy for regulating the catalytic activity, selectivity, and stability toward electrocatalytic reduction of CO2 (ECO2R). However, rational design and deliberate fabrication of SACs with axial coordination of specified atoms remain challenging. Herein, Ni single atoms with axial coordination of phosphorus (NiP−N4−C) and four planar nitrogen atoms are fabricated, which induces reorientation of the 3d orbitals of the Ni atom and shift of the spin state from low (S = 0) to high (S = 2). The enhanced d−p orbital coupling between the Ni and the adsorbents enhances CO2 activation and reduces energy barrier for formation of *COOH, a key intermediate in the ECO2R to produce CO, enabling the high activity and near unity selectivity of CO in ECO2R in a broad potential range of 600 mV (−0.4–−1.0 V vs reversible hydrogen electrode vs RHE), achieving a turnover frequency of 37.2 s−1 at −1.0 V versus RHE. As a bifunctional cathode electrocatalyst, NiP−N4−C demonstrates a peak power density of 18.5 mW cm−2 and maintains cycling durability over 70 h in rechargeable Zn−CO2 batteries.

Electrocatalysis can synthesize valuable chemicals and plays a vital role in developing clean and renewable energy storage and conversion devices. In traditional electrocatalytic systems, researchers have attempted to independently synthesize one type of valuable chemical at the cathode or anode. Recently, the electrocatalytic bipolar synthesis of valuable chemicals at both the cathode and anode has become popular and has attracted much attention. In this minireview, we summarize the latest processes on innovative strategies for the electrocatalytic bipolar synthesis of various chemicals. We will discuss the findings according to the categories of the products, including bipolar hydrogen production, bipolar formate production and bipolar hydrogenation. The associated catalyst optimization, reaction mechanism, and design principles are well described. Moreover, the challenges and prospects for future developments are highlighted. This review is timely and will guide others to pay more attention to these novel electrocatalytic bipolar synthesis systems.
